The lack of a functional adaptive immune system in these altricial young raises questions about how they survive in a microbe-rich environment. Previous studies on marsupial pouches have revealed changes to pouch microbe composition during lactation, but no information is available in monotremes. We investigated changes in the echidna pseudo-pouch microbiota (n = 22) during different stages of the reproductive cycle and whether this differs between wild and zoo-managed animals. Metataxonomic profiling using 16S rRNA gene sequencing revealed that pseudo-pouch microbial communities undergo dramatic changes during lactation, with significant differences in taxonomic composition compared with samples taken outside of breeding season or during courtship and mating. This suggests that the echidna pseudo-pouch environment changes during lactation to accommodate young that lack a functional adaptive immune system. Furthermore, captivity was not found to have a significant effect on pseudo-pouch microbiota. This study pioneers pouch microbiota research in monotremes, provides new biological information on echidna reproduction, and may also provide information about the effects of captive management to inform breeding programmes in the future.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12001884/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsurface microbial communities accelerate this process at circumneutral pH directly by weathering pyritic surfaces and indirectly by causing changes to the surrounding microenvironment, thereby further accelerating pyrite weathering. However, our understanding of community structure dynamics and associated biogeochemistry in Fe- and S-rich lithologies, e.g. pyritic coal, is limited. Here, we present the first comprehensive regional and seasonal genus-level survey of bacterial groundwater communities in a pyritic coal-based aquifer in the South Wales Coalfield (SWC), using 16S rRNA gene amplicon sequencing. Seasonal changes in community structure were limited, suggesting limited influence of surface processes on subsurface communities. Instead, hydrogeologically distinct mine water blocks (MWB) and coal rank largely explained bacterial community structure variation across sites. Fe(II)-oxidizing Betaproteobacteriales genera Gallionella and Sideroxydans dominated the bacterial communities across nine sites and seven MWBs, while three sites within a single MWB, were dominated by S-oxidizing Epsilonbacteraeota genera Sulfuricurvum and Sulfurovum. The cooccurrence of pairs of Fe(II)- and S-oxidizing bacterial genera suggests functional redundancy, which coupled with genus-specific morphologies and life strategies, indicates the importance of distinct environmental and ecological niches within the SWC groundwater at seasonal and regional scales.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"101 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12001885/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143991890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the fitness benefit has not been explored quantitatively. Here, three existing mathematical models are extended to include EVs and parameterized based on literature. Simulations include a number of environments (lab culture and ambient), conditions (equilibrium and oscillating, i.e. predator-prey cycles), and bacteria (including enteric Escherichia coli and marine Prochlorococcus). Hosts invest, on average, ∼10% of resources into EV production. The models predict that producing EVs typically results in relatively minor increases in average host concentration (average ∼4.3% of log concentration). However, under oscillating conditions, EVs can substantially dampen and, in most cases, completely eliminate fluctuations, thereby increasing the minimum concentration and reducing extinction risk. These results provide insights into the fitness benefit of EVs as viral countermeasures, and they constitute a starting point for including EVs in ecosystem models.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"101 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11995696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143999253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we isolated and characterized seven new lytic phages and compared their genomes with those of their closest relatives. Gene-sharing network, ViPTree proteome, and terL gene-sequence-based analyses incorporating all publicly available webervirus genomes [n = 258 from isolates, n = 65 from metagenome-assembled genome (MAG) datasets] confirmed the seven phages as members of the genus Webervirus and identified a novel genus (Defiantjazzvirus) within the family Drexlerviridae. Using our curated database of 265 isolated phage genomes and 65 MAGs (n = 330 total), we found that weberviruses are distributed globally and primarily associated with samples originating from the gut: sewage (154/330, 47%), wastewater (83/330, 25%), and human faeces (66/330, 20%). We identified three distinct clusters of potential depolymerases encoded within the 330 genomes.

To promote water recycling and reuse associated with oil reservoirs produced by hydraulic fracturing, high-salinity produced waters are temporarily stored in surface ponds prior to subsequent reinjection into the subsurface. In this study, nitrate was added directly to a storage pond to prevent sulfide accumulation. DNA sequencing of pond water over a 4-week period revealed a decrease in the proportion of sulfate-reducing microorganisms following nitrate application. Sulfate levels remained stable during this period, whereas nitrate and nitrite fluctuated in the days following the nitrate addition. Metagenome-assembled genomes (MAGs) reconstructed from the pond water microbiome highlighted different organisms with genes for organoheterotrophic and lithoheterotrophic nitrate reduction, whereas genes associated with sulfide production via sulfate or thiosulfate reduction were barely detected. Within those MAGs, genes for acetate metabolism were observed, consistent with acetate decreasing substantially in the pond water in the presence of nitrate. After nitrate was consumed an increase in relative abundance of putative autotrophic microorganisms was observed (e.g. Arhodomonas, Guyparkeria, and Psychroflexus), corresponding to a drop in total inorganic carbon measurements in the storage pond. This trial offers an overview on microbial processes taking place in storage pond environments in response to nitrate addition.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"101 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12047076/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In animals, microbes commonly occupy the gut and may supply critical nutrients. The leaf-footed bug, Leptoglossus zonatus (Coreidae), is a true bug that is dependent upon ingestion of the free-living, soilborne bacterium Caballeronia early in development for growth and reproduction. In 2019 and 2020, we tested the ability of second instar L. zonatus to acquire Caballeronia in the canopy of pomegranate trees where L. zonatus are often found. We compared the acquisition rate of Caballeronia in nymphs left to forage for the symbiont to bugs fed Caballeronia in advance. Additionally, we aimed to determine whether the microhabitat of potential symbiont sources influenced acquisition success. We hypothesized that the acquisition rate would be heterogeneous among treatments. In 2019, ∼30% of experimental bugs acquired Caballeronia, compared to 75% of those fed the symbiont. In 2020, only about 4% of experimental bugs acquired any symbiont. The symbiont composition of caged bugs differed, and strain diversity was reduced relative to wild bugs. We concluded that Caballeronia is present in the canopy environment, but nymphs may fail to acquire it in the fragments of habitat represented by caged branches, suggesting a cost to host dependency on environmentally acquired symbionts.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"101 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12063585/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143994346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, there is no consensus on the criteria for assessing microbiome resilience. This article provides new insights into the metrics and techniques for resilience assessment. We discussed several potential parameters, such as microbiome structure, keystone species, biomarkers, persistence degree, recovery rate, and various research techniques in microbiology, metagenomics, biochemistry, and dynamic modeling. The article further explores the factors that influence the gut microbiome resilience. The microbiome structure (i.e. abundance and diversity), keystone species, and microbe-microbe interplays determine microbiome resilience. Microorganisms employ a variety of mechanisms to achieve the microbiome resilience, including flexible metabolism, quorum sensing, functional redundancy, microbial cooperation, and competition. Host-microbe interactions play a crucial role in maintaining microbiome stability and functionality. Unlike other articles, we focus on the regulation of host immune system on microbiome resilience. The immune system facilitates bacterial preservation and colonization, community construction, probiotic protection, and pathogen elimination through the mechanisms of immunological tolerance, immune-driven microbial compartmentalization, and immune inclusion and exclusion. Microbial immunomodulation indirectly modulates microbiome resilience.","PeriodicalId":12312,"journal":{"name":"FEMS microbiology ecology","volume":"101 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12065411/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143975744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that bacterial isolates exhibited a strong phylogenetic signal in their growth responses, with closely related taxa responding similarly to chemical stress. In microbial communities, pollutants that significantly impacted isolates also reduced community diversity and growth, causing shifts in community structure toward increased phylogenetic clustering, suggesting environmental filtering. The mean phylogenetic distance effectively captured these shifts, indicating its potential as a simple metric for monitoring pollution.
